Google, without a doubt, is still the world's most commonly used search engine. From this, we can only logically conclude that if only a small percentage of people use Google, and you come across them, it implies potential prospects for your business, which holds significant importance for having your enterprise appear on the results page of the most commonly used search engine.
Especially in the Australian market, Google has a stronger market share than it does in the U.S., with approximately 90% of the market share. This practically means that we don't actually use the other two lower-level search engines, Yahoo! and Windows Live Search. In other words, the searches conducted on these other two search engines are at minimal levels, making their contribution to traffic reaching your website much smaller compared to Google. There aren't any definitive numbers since they depend on industry and target market, but these numbers could lie anywhere between 2-5% (if your site ranks well on those other search engines).
It's crucial to understand that completely eliminating focus from Yahoo! and Windows Live Search engine optimization isn't necessary; however, strong rankings on these can be seen as some form of penalty. Consider this scenario: Your site ranks well on the other two lower-level search engines while maintaining a strong presence on Google. You might immediately react by requesting to shift focus back to strongly ranking on those other two search engines. But perhaps, it would be more meaningful to focus on the search engine that accounts for 90% of search traffic possibly reaching your site.
Given that any organization will have limited time and resources to allocate to SEO projects, would you prefer spending valuable time increasing traffic by 2% or achieving double-digit growth by focusing on Google search engine optimization?
In cyberspace, there are so many "measurable indicators" available to people, sometimes people lose focus, allocating attention to the wrong content, and things don't necessarily have a positive impact on your business' bottom line. The bottom line is, different markets require different tactics, and in Australia, due to consumer habits, Google search engine optimization is the primary tactic that will positively impact the traffic level reaching your company's website, improving your ranking on Google's result pages.
